Description 描述

Make a horizontal scrollbar. Scrollbars are what you use to scroll through a document. Most likely, you want to use scrollViews instead.

创建水平滚动条。滚动条是能通过滚动来浏览文档，大多数情况下，你可以使用scrollView代替。

JavaScript:

	var hSbarValue : float;
 
	function OnGUI () {
		hSbarValue = GUI.HorizontalScrollbar (Rect (25, 25, 100, 30), hSbarValue, 1.0, 0.0, 10.0);
	}

Finding extra elements:

The styles of the buttons at the end of the scrollbar are searched for in the current skin by adding “leftbutton” and “rightbutton” to the style name. The name of the scrollbar thumb (the thing you drag) is found by appending “thumb” to the style name.

滚动条两端的按钮的样式是在当前皮肤中搜索 “leftbutton”和“rightbutton”样式名字确定。滚动条滑块的样式是搜索 “thumb”的样式名。

JavaScript:

var scrollPos : float = 0.5;
	// This will use the following style names to determine the size / placement of the buttons
	// MyScrollbarleftbutton    - Name of style used for the left button.
	// MyScrollbarrightbutton - Name of style used for the right button.
	// MyScrollbarthumb         - Name of style used for the draggable thumb.
	function OnGUI() {
		scrollPos = GUI.HorizontalScrollbar(Rect(0,0,100,20), scrollPos, 1, 0, 100, "Scroll");
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public float hSbarValue;
    void OnGUI() {
        hSbarValue = GUI.HorizontalScrollbar(new Rect(25, 25, 100, 30), hSbarValue, 1.0F, 0.0F, 10.0F);
    }
}
